RS PRO Signal Conditioner, Voltage Input, Current Output, 24 → 230V ac Supply

RS Pro single or dual trip amplifiers with the facility to arrange each trip so that the alarm condition can be above (high trip) or below (low trip) the set point. The relay can be either energise/de-energise in the alarm condition (fail-safe) or de-energise/energise in the alarm condition (non-fail safe).

Dual supply voltage operation
Bi-colour LED status indication
Front panel adjustment of "Trip Levels"

Input and output stages powered from separate secondaries of the supply transformer to provide 3-port isolation
Dual supply voltage operation
LED indication of "power on"

Trip settings are set via links on a PBC within the unit,Signal isolators/Converters; Four units which provide signal isolation via an opto-isolated hybrid circuit. The 0-10Vdc; 4-20mA;and 4-20mA; 0-10Vdc units also convert process signals into a required standard transmission voltage or current signals
